The forewing markings of  T. emarginataalso resemble those of  T. pediformis, but the short streak present near the tornus of  T. emarginatais absent in the latter. The male genitalia of  T. emarginataare diagnosed by the valva emarginate at distal 1/3 of the ventral margin. The female genitalia could be confused with those of  T. pediformis, but the anterior margin of sternum VIII is broadly U-shaped in  T. emarginatawhereas it is narrowly U-shaped in the latter species.   Description.Adult ( Fig. 19C). Wingspan 7.5−11.0 mm. Head glossy white. Labial palpus white, with segment I very short; segment III fuscous ventrally and apically, slightly longer than II. Antenna with scape glossy white; flagellum dark fuscous except basal 1/3 or 1/4 of dorsal surface white, male cilia as long as diameter. Thorax and tegula glossy white. Forewing glossy white or creamy white, anterior edge of costa black in basal 1/3 or 1/2, markings dark fuscous: a wedge-shaped costal streak from between distal 1/4 and 1/3 of wing, attenuated distally, obliquely running toward apex and nearly reaching apical spot, followed by and confluent with a shorter costal streak extended from distal 1/5; beyond this suffused with light brown scales before apex; apical spot round or elliptical, sometimes shortly extending along termen as a slender line, its inner margin slightly suffused with grey; a grey suffusion along dorsum from near base to 2/3, followed by an inwardly directed V-shaped marking, the upper fork of this nearly reaching apical spot and often confluent with costal streaks, the lower fork much shorter and running along fold; a short dark longitudinal streak near tornus, running almost in parallel with the lower fork of former marking but not reaching it; fringe on apical area creamy white with subterminal and terminal black bands, produced downwards and bifurcate; fringe on termen grey except basal half white, near apex with a row of coarse metallic fuscous ciliation; fringe on dorsum whitish grey. Hindwing grey except subapex white and apex black; fringe whitish grey except apical area white with a terminal black band. Legs white; fore coxa suffused with fuscous in anterior 2/3; fore femur, tibia and tarsus fuscous on outer surface; mid and hind tibiae with a short dark fuscous streak near apex, respectively; mid and hind tarsi with first tarsomere broadly dark fuscous at middle, II–III tarsomeres dark fuscous in basal half.  Abdominal segments( Figs 27D, 28B). In male, sternum VIII 1/5 length of abdomen; lateral margins deeply concave in basal 4/5, then convex posteriorly; posterior 1/3 bifurcate, inner margin of two tines forming a U-shape, somewhat pointed apically; tergum VIII sclerotized as a trapezoidal plate, bearing long coremata bilaterally and large petal-like scales mediolaterally. In female, posterior margin of tergum VII deeply concave in V-shape and shortly sclerotized, with a bundle of stiff scales.  Male genitalia( Figs 42F, 43H). Uncus broad, mitre-shaped. Gnathos hook long and very slender. Tegumen 1.5 times as long as uncus, with a median line near anterior margin. Valva broad, slightly curved outward distally; ventral margin broadly convex in basal 2/3, emarginate at 2/3, then bulged before apex; apex narrowed, truncate. Anellus lobe short, ditigate, sparsely setose. Juxta strongly convex medially, hummock-like. Vinculum simple, narrowed. Saccus very short and slender, elongate sub-triangular, rarely bifurcate apically. Aedeagus narrowing from base to apex, constricted at basal 2/5 and before apex, respectively, rounded at apex.  Female genitalia( Fig. 59E). Papillae anales weakly sclerotized. Apophyses anteriores approximately 1/2 length of apophyses posteriores. Sternum VIII longer than tergum VIII, weakly sclerotized except anterior and posterior margins; anterior margin broadly U-shaped. Ostium bursae opening near anterior margin of sternum VIII. Ductus bursae narrowed in basal 1/3 or 2/5, then abruptly broadened, with a linear sclerite arising from base and reaching colliculum; colliculum situated near base, ductus seminalis arising from posterior 1/3 or 2/5. Corpus bursae elliptical, slightly longer than ductus bursae, rarely 3 times as long as ductus bursae; signum rounded, consisting of minute denticles, placed at posterior 2/5 or 1/3.   Distribution. China( Anhui, Fujian, Guangdong, Guangxi, Hainan, Hunan, Jiangxi, Yunnan, Zhejiang).   Etymology.The species name is from Latin, emarginatus(emarginate), referring to the emarginate distal 1/3 of valva.   Remarks.The species name was suggested by Jialiang Zhang who previously studied Chinese  Thiotrichain NKU. 2016-08-07 Qingyun Wang & Meiqing Yang & Ping Liu Jiangshan City 424 28.35 Laofoyan Village 739 118.63 Shuangxikou Town 131 132 1 1 Zhejiang Province holotype [289,1431,546,573] 2016-08-07 2016-08-09 2016-08-07 Qingyun Wang & Meiqing Yang & Ping Liu China Jiangshan City 424 28.35 Laofoyan Village 739 118.63 Shuangxikou Town 131 132 26 11 15 Zhejiang paratype [507,1265,582,609] 1999-08-15 Houhun Li China 350 Mt.
